Purpose. Impaction fractures of the anterior aspect of the humeral head, the reversed Hill-Sachs lesion, are common in posterior shoulder dislocation. We present a new technique to address these lesions arthroscopic-assisted with the use of a bone substitute. Methods. We report the case of a 45-year-old male with a reversed Hill-Sachs lesion after posterior shoulder dislocation. Initially a glenohumeral arthroscopy is performed to address concomitant intra-articular injuries. Guided by the k-wire a cannulated sizer was inserted for reduction of the fracture under arthroscopic visualization. For reduction of the impacted part of the humeral head the subcortical defect was filled with an injectable bone substitute (Cerament) to prevent secondary dislocation. Results. X-ray at follow-up 6 months after the index procedure documents the bony remodeling of the bone substitute. At that time the patient was pain-free (VAS 0) and satisfied with the outcome (Constant score: 78, Rand-36 score: 84, Rowe score: 81) with a good ROM. Conclusions. In conclusion, arthroscopic-assisted reconstruction of reversed Hill-Sachs lesions with an injectable bone substitute is feasible and may provide patients with all the benefits of an anatomic reconstruction with decreased risks related to open surgery.

Cimetidine, an H-2 antagonist, is one of the most commonly prescribed drugs and is used in the management of peptic ulcer disease and prevention of stress ulcerations following major trauma or operations. It has been shown that histamine has a stimulatory effect on wound healing which is believed to be mediated through H-2 receptors. We hypothesized that cimetidine would have an inhibitory effect on wound healing. Fifty-two adult rats were divided into two groups: Group A was placed on a standard chow and Group B was given chow supplemented with cimetidine (300 mg/Kg diet), a dose equivalent to that clinically used in man and effective in inhibiting gastric hypersecretion in the rat. Ten days later, all rats underwent a dorsal skin incision under pentobarbital anesthesia and implantation of a polyvinyl alcohol sponge subcutaneously. Animals were maintained on their respective diets. Rats were killed with ether five and ten days postoperatively, the wounds were excised and breaking strength measured. Sponge hydroxyproline content was measured. No significant difference in breaking strength or sponge hydroxyproline content was found between the two groups. We thus conclude that cimetidine has no effect on wound healing in rats when used in doses equivalent to the clinical dose in man. [ABSTRACT FROM AUTHOR]

We report a case of a professional soccer player suffering from a traumatic cartilage lesion grade IV according to the Outerbridge classification at the femoral condyle treated with an enhanced microfracture technique (AMIC). Autologous Matrix-Induced Chondrogenesis (AMIC) is an innovative treatment for localized full-thickness cartilage defects combining the well-known microfracturing with collagen scaffold and fibrin glue. Because of the cartilage lesion (3 cm2), an AMIC procedure was performed followed by a rehabilitation program according to the protocols in the literature, (Steadman et al.; 2003). After 8 months of rehabilitation, the player returned to team training and after 10 months to competition. Altogether he returned to the same skill level for almost one year after the index operation. He is very satisfied with the clinical results after AMIC, which corresponds with the Lysholm score of 90 points at 12 months. [ABSTRACT FROM AUTHOR]
